Solar power installation, self-consumption, and effective utilization of electricity.
The ECube 200B is a direct current energy storage system for industrial and commercial use, equipped with a storage capacity of 200.7 kWh. By collaborating with solar power generation, it stores the generated electricity and utilizes it during necessary time periods, contributing to the effective use of renewable energy and the expansion of self-consumption. It employs lithium iron phosphate (LFP) batteries, which are long-lasting and highly safe, achieving a cycle life of 8,000 cycles (80% DoD). Constant monitoring and active balancing functions provided by the built-in BMS support stable operation. Additionally, it accommodates flexible system configurations with various PCS. With forced air cooling, aerosol fire extinguishing equipment, and an IP54 protection design, it is also suitable for outdoor installation in factories and commercial facilities.

Applications/Examples of results
1. Factories and Manufacturing Facilities Combined with solar power generation equipment, the generated electricity is stored and utilized for self-consumption. We support energy management that aligns with electricity usage time periods. 2. Office Buildings and Commercial Facilities Excess solar power generated during the day is stored and used during necessary time periods, such as in the evening. This contributes to reducing purchased electricity and improving the efficiency of electricity usage. 3. Multi-family Housing By combining solar power generation and storage batteries, we promote the use of renewable energy within the building. The above are examples of potential applications. The actual implementation effects may vary depending on system configurations such as PCS, installation conditions, and operational methods.
